Prehistoric culture diffusion in the Gran Chichimeca PublicDeposited

Descriptions

The Gran Chichimeca is a North American area extending from
the Tropic of Cancer to the south to the thirty-eighth parallel in
the north, thus embracing northern Mexico and the American Southwest.
The rise of the great mesoamerican civilizations to the south
of the Gran Chichimeca and the consequent pressure of trade resulted
in a northward diffusion of cultural traits, many of which reached
the American Southwest.
The advantages of various possible routes over which mesoamerican
cultural traits might have been passed are discussed and
five specific traits are examined. In the American Southwest, especially,
these traits are but dimly perceived and are not accorded the
recognition which they merit.
These traits have been selected for their unique character
and their patent visibility. The character of these five traits and
their significance is demonstrated.
